  • Patent number: 8965034
    Abstract: [Problems] To provide a multifunction vibration actuator which has flat rising and falling frequency characteristic at the time of generation of bodily sensation vibration and which is stable for an input signal. [Means for Solving Problems] Flat frequency characteristics can be obtained by using a two-fold rotational symmetry frame type suspension, and miniaturization of the whole multifunction vibration actuator can be made by the user of the frame type suspension. With regard to the frame type suspension, use of protruded configuration of corner parts ensures the effect of absorption of deflection of the suspension.
    Type: Grant

  • Publication number: 20140153771
    Abstract: Provided is a multi-functional type vibration actuator capable of stabilizing behavior of a magnetic circuit unit by preventing stress from concentrating on a connecting portion in a frame-shaped suspension. In the frame-shaped suspension, a plurality of support portions are formed to configure the connecting portion, and a strength of the connecting portion is improved by a suspension fixing portion and the support portions, thereby stabilizing the behavior of the magnetic circuit unit.
